Overview

Image: Flow of effectiveness of new lightning prevention system

In recent years, heavy rain and lightning has increased associated with changes in the global environment, such as global warming, extreme weather, heat islands, and other phenomena. Therefore, with the achievement of advanced precision electronic equipment in modern society, preventing equipment damage and breakdowns caused by direct lightning strikes or surges caused by nearby lightning strikes has become a major issue.

Image: We have installed over 205 systems in Japan, also experienced the first overseas installation in 2009. (as of March 2010).We will expand the overseas applications for the future.

We have installed over 205 systems to prevent lightning surge damage by preventing direct lightning strikes, which was not possible with conventional lightning rods, and there have been zero reports of direct lightning strikes (as of March 2010).

Features
